<p>A film for preventing refractory deterioration is formed on the surface of refractory of a refuse incinerator. Since the preventive film exhibits high adhesion resistance to clinker generated in the incinerator, clicker does not adhere to the film easily. Since the preventive film is composed of a compact inorganic oxide based ceramics, surface layer of a brick body is covered with a film harder than the body. Consequently, wear resistance of refractory brick is enhanced. Since a corrosion resistant film exists on the surface of the body, intrusion of chloride gas is suppressed effectively even if the body is exposed to chloride gas. Even if an inexpensive fireclay brick is protected against adhesion of clinker and spalling, and use period of refractory brick is prolonged.</p> |
